Statistics.Matrix.Mutable

Description

Basic mutable matrix operations.

Synopsis

Documentation

data MMatrix s #

Two-dimensional mutable matrix, stored in row-major order.

Constructors

MMatrix !Int !Int !Int !(MVector s) 

type MVector s = MVector s Double #

replicate :: Int -> Int -> Double -> ST s (MMatrix s) #

thaw :: Matrix -> ST s (MMatrix s) #

bounds :: MMatrix s -> Int -> Int -> (MVector s -> Int -> r) -> r #

Given row and column numbers, calculate the offset into the flat row-major vector.

unsafeNew #

Arguments

:: Int

Number of row

-> Int

Number of columns

-> ST s (MMatrix s) 

Allocate new matrix. Matrix content is not initialized hence unsafe.

unsafeRead :: MMatrix s -> Int -> Int -> ST s Double #

unsafeWrite :: MMatrix s -> Int -> Int -> Double -> ST s () #

unsafeModify :: MMatrix s -> Int -> Int -> (Double -> Double) -> ST s () #

immutably :: NFData a => MMatrix s -> (Matrix -> a) -> ST s a #

unsafeBounds :: MMatrix s -> Int -> Int -> (MVector s -> Int -> r) -> r #

Given row and column numbers, calculate the offset into the flat row-major vector, without checking.
